Description

BESCHREIBUNGDESCRIPTION

Die Neuerung betrifft eine Verbindung von Holzwerkstoffen und Werkstoffen jeder Art mit Hilfe von Klebern zur Aufnahme von Zug- und Druckkräften, sowie Querkräften und Momenten.The innovation concerns a connection of wood materials and materials of any kind with the help of adhesives to absorb tensile and compressive forces, as well as transverse forces and moments.

Es ist bekannt Verbindugen von Holz mit Stahlblechen durch vernageln, verbolzen oder verdübeln herzustellen. Hierzu werden die Holzwerkstoffe vorgefertigt geschlitzt und anschließend das Stahlblech durch Bolzen, Dübel oder dergleichen mit dem Holzwerkstoff verbunden.It is known to connect wood to steel sheets by nailing, bolting or dowelling. To do this, the wood materials are prefabricated and slotted and then the steel sheet is connected to the wood material using bolts, dowels or the like.

Als Nachteil derartiger Verbindungen hat sich herausgestellt, daß die Vorfertigungen im Holzwerkstoff anschließend nicht mit dem Stahlblech oder Dübeln übereinstimmen. Dieses ist in erster Linie dadurch begründet, daß Holz infolge seines hetrogenen Wachstums ständig arbeitet. Wasser, Dampf, Witterungseinflüsse etc. bedingen in Grenzen Schwankungen im Holzwerkstoff, sodaß Bohrungen, Schlitze etc. ständig einem Mindermaß oder Übermaß unterworfen sind. Dadurch bedingt können Holz und Stahl nicht in großen Mengen vorgefertigt werden, sodaß die Werkstoffe erst nach Anlieferung miteinander verbunden werden.A disadvantage of such connections has been found to be that the prefabricated parts in the wood material do not match the steel sheet or dowels. This is primarily due to the fact that wood is constantly moving due to its heterogeneous growth. Water, steam, weather influences, etc. cause fluctuations in the wood material within certain limits, so that holes, slots, etc. are constantly subject to under- or over-dimensions. As a result, wood and steel cannot be prefabricated in large quantities, so that the materials are only connected to one another after delivery.

Technisch ungelöst ist auch das Problem von Bohrungen die in Holz und Stahl gleichzeitig ausgeführt werden. Dieses liegt an den unterschiedlichen Spänen beim Bohren. Trifft ein Bohrer nach dem Bohren von Holz auf Stahl, so beschädigen die Stahlspäne die Lochwandung im Holz und es kann anschließend beim Verdübeln keine korrekte statische Aussage darüber gemacht werden, wie die Kräfte in der Verbindung verlaufen.The problem of drilling holes in wood and steel at the same time is also technically unsolved. This is due to the different chips produced when drilling. If a drill bit hits steel after drilling wood, the steel chips damage the hole wall in the wood and no correct static statement can be made about how the forces in the connection are distributed when dowelling.

Es ist auch bekannt Verbindungen zwischen Holz und Stahl durch Kleber herzustellen. Sachdienliche Angaben macht das Forschungsvorhaben 14-36287 der Forschungs- und Materialprüfungsanstalt Baden-Württembergs über "Kostensparende Holzverbinungen durch eingeleimte Metallbleche unter Verwendung neuartiger Kleber mit erhöhter Leimfugendicke". Das Forschungsvorhaben gibt zwar die Verwendungsmöglichkeit von Klebstoffen an, zeigt jedoch keine Lösungsmöglichkeit für die Herstellung der Verbindung.It is also known to create connections between wood and steel using adhesives. The research project 14-36287 of the Research and Materials Testing Institute of Baden-Württemberg provides relevant information on "Cost-saving wood connections using glued metal sheets using new types of adhesives with increased glue joint thickness". The research project does indicate the possibility of using adhesives, but does not show a possible solution for creating the connection.

Aufgabe der Neuerung ist es eine Verbindung zwischen Holzwerkstoffen und Werkstoffen jeder Art zu schaffen, die die vorherig erwähnten Nachteile nicht aufweist.The aim of the innovation is to create a connection between wood materials and materials of any kind that does not have the previously mentioned disadvantages.

Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale des Hauptanspruches. In den Unteransprüchen werden Sonderlösungen aufgezei gt.The problem is solved by the characteristic features of the main claim. Special solutions are shown in the subclaims.

Hierdurch wird erreicht, daß zunächst der oder die Schlitze im Holzwerkstoff erstellt werden. Diese Schlitze können verschiedenste Gestalt haben. Sie können gerade, wellig, in Axial richtung gebogen oder gekrümmt sein. Dies ist abhängig von dem Werkstoff und dem Verwendungszweck der Verbindung.This means that the slot(s) are first created in the wood material. These slots can have a wide variety of shapes. They can be straight, wavy, bent in the axial direction or curved. This depends on the material and the intended use of the connection.

In die so vorbereiteten Schlitze werden die entsprechenden Flachkörper aus Stahl, Kunststoff oder dergleichen eingesetzt und verklebt. Hierdurch entsteht eine sichere Verbindung, die sowohl Zug- und Druckkräfte, sowie Querkräfte und Momente aufnimmt und weiterleitet. Die Flachkörper sind so dimensinoniert, daß sie das natürliche Schwind- und Quellverhalten der Holzwerkstoffe ohne Beeinträchtigung der Kraftübertragung zulassen. Völlig überraschend hat sich herausgestellt, daß die Schlitze im Holz vorgefertigt werden können und erst vor dem Einbau die Verbindung mit dem Flachkörper kostengünstig erstellt wird. Witterungsbedingte Volumenänderungen des Holzwerkstoffes oder solche durch Nässe oder Dampf sind ohne Einfluß auf die Verbindung mit dem Festkörper. Darüberhinaus ist der oder die Anteile der Flachkörper geringer als bei den bekannten Verbindungen. Desweiteren ist der oder die Flachkörper der neuerungsgemäßen Verbindung von Holzwerkstoff ummantelt und bietet somit in Brandfällen eine größere Standsicherheit.The corresponding flat bodies made of steel, plastic or similar are inserted into the slots prepared in this way and glued. This creates a secure connection that absorbs and transmits both tensile and compressive forces, as well as transverse forces and moments. The flat bodies are dimensioned in such a way that they allow the natural shrinkage and swelling behavior of the wood materials without affecting the force transmission. It has been found, quite surprisingly, that the slots can be prefabricated in the wood and the connection to the flat body is only created cost-effectively before installation. Changes in the volume of the wood material due to weather or moisture or steam have no influence on the connection to the solid body. In addition, the proportion of flat bodies is smaller than in the known connections. Furthermore, the flat body of the new connection is covered by wood material and thus offers greater stability in the event of a fire.

Ein Ausführungsbeispiel der neuerungsgemäßen Verbindung ist in den Figuren 1.,2.,3. und 4. dargestellt und wird im folgenden näher beschrieben.An embodiment of the connection according to the innovation is shown in Figures 1, 2, 3 and 4 and is described in more detail below.

Es zeigt Figur 1. den Holzwerkstoff mit den vorbereiteten Schlitzen und Figuren 2.,3. und 4. verschiedene Ausführungsformen der Flachkörper der Verbindung.Figure 1 shows the wood material with the prepared slots and figures 2, 3 and 4 show different designs of the flat bodies of the connection.

Figur 1 offenbart beispielhaft den Holzwerkstoff 7 mit vorbereiteden verschiedenen Schlitzformen 1,1',2,2',3. Die Schlitze 1,1',2,2',3 können durch bohren, fräßen, sägen oder dergleichen in dem Holzwerkstoff 7 eingebracht werden. Sofort nach Erstellung der Schlitze oder auch erst wesentlich später, beim Einbau wird in die Schlitze ein vorbereiteter Kleber eingebracht und die Flachkörper 4,5,6 in die im Holzwerkstoff 7 vorbereiteden Schlitze 1,1',2,2',3 eingesetzt. Nach der Aushärtung des Klebers wird der so vorbereitete Holzkörper eingesetzt. Hierdurch wird die Serienfertigung einschließlich der Schlitze 1,1',2,2',3 in holzbearbeitenden Betrieben oder dergleichen ermöglicht während das Einbringen der Festkörper 4,5,6 hiervon unabhängig wesentlich später am Einsatzort erfolgen kann, ohne daß Witterungseinflüsse sich nachteilig auf die kraftschlüssige Verbindung auswirken.Figure 1 shows, by way of example, the wood material 7 with prepared different slot shapes 1,1',2,2',3. The slots 1,1',2,2',3 can be made in the wood material 7 by drilling, milling, sawing or the like. Immediately after the slots have been created or even much later, during installation, a prepared adhesive is introduced into the slots and the flat bodies 4,5,6 are inserted into the slots 1,1',2,2',3 prepared in the wood material 7. After the adhesive has hardened, the wooden body prepared in this way is inserted. This enables series production including the slots 1,1',2,2',3 in woodworking companies or the like, while the introduction of the solid bodies 4,5,6 can take place independently of this much later at the place of use, without weather influences having a detrimental effect on the force-fit connection.

Es ist durchaus denkbar, daß nicht alle Schlitzformen benötigt werden, sondern nur eine Schlitzform für die sichere Verbindung benötigt wird.It is quite conceivable that not all slot shapes are needed, but only one slot shape is required for a secure connection.

Zur besseren Haftung des Flachkörpers 5 in dem Holzwerkstoff 7 sind beispielhaft Löcher 8 vorgesehn. Es ist aber auch denkbar, daß der Reibungsbeiwert durch die Aufrauhung 9 der Oberfläche, wie beispielhaft im Flachkörper 4 dargestellt, erhöht wird.For better adhesion of the flat body 5 in the wood material 7, holes 8 are provided for example. However, it is also conceivable that the coefficient of friction is increased by roughening 9 of the surface, as shown for example in the flat body 4.

Nachdem erstellen der Verbindung besteht die Möglichkeit die Flachkörper 5,6,7 , die Oberfläche des Holzwerkstoffes überragen zu lassen und zur Verbindung mit anderen Werkstoffen jeder Art zu benutzen.After the connection has been created, it is possible to allow the flat bodies 5,6,7 to protrude beyond the surface of the wood material and to use them to connect with other materials of any kind.
